subir gifRolex has decided to resurrect the term “Superlative Chronometer ” with the introduction of caliber 3255, its newest generation mechanical movement that equips the new Day-Date. According to the manufacturer, “Rolex has established a level of chronometric precision that surpasses the level defined by COSC criteria. The new Day-Date’s precision on the wrist satisfies criteria twice as exacting as those for an officially certified chronometer, reconnecting with the brand’s heritage and restoring full weight to the notion of Superlative Chronometer.”
The new caliber 3255 Day-Date movement utilizes technology that takes advantage of no less than 14 Rolex patents. Oscillating at a rate of 4Hz (28,800 vph), this 31 jewel, bi-directional self-winding movement does not use a higher rate to increase chronometric precision. Instead, they make horolgical innvoations to improve chronometry. From the paramagnetic blue Parachrom hairspring, to the state-of-the-art Chronergy escapement with Paramagnetic nickel-phosphorus pallet fork and escape wheel, to the large balance wheel with variable inertia weights, to the high performance Parallax shock absorbers and the traversing balance bridge – the caliber 3255 epitomizes 21st century chronometry.
Caliber 3255 is not only more accurate than its predecessors, it is also more efficient, resulting in an impressive 70-hour power reserve. And it is a Rolex, so it of course, defines reliability. Further, effective July 1, 2015, the international Rolex warranty is now 5-years, backing up their reputation as one of the most robust and reliable watches being produced.
